Variables

Public

Name Type Remarks Include Path Unreal Specifiers    
AddSamplesForCollision bool If enabled, add extra vertices (without triangles) to the geometry in regions where vertices are spaced too far apart (e.g. across large triangles) These extra vertices will be used as collision samples in particle-implicit collisions, and can help the physics system detect collisions more accurately Dataflow/GeometryCollectionUtilityNodes.h

bFractureLevelIsAll bool Helper variable to let the EditConditions above check whether the Fracture Level is set to 'All' Dataflow/GeometryCollectionUtilityNodes.h
